Sounds like you are a talented person to make all of those parts.
IMHO, Southern mountain guns are pretty late for a round face lock. IMHO, a Chambers late Ketland would be more appropriate for an 1790 or later gun, which is the time period for Southern mountain rifles.
Chuck sure does have the English style guns down, doesn't he. His guns are a variation of the "Woodberry school" of modern interpretation of southern schools.
IMHO, Chuck's guns show more inspiration from original guns than most Woodberry guns. Some of Chuck's work is pretty close to the originals that provide inspiration for his work. Some, not so much.
I haven't used the L&R Queen Anne lock, so I can't give an honest critique. I know that Chuck sometimes uses them, but I don't know how much work he puts into them.
I seem to remember someone mentioning that the Queen Anne lock had a problem of catching on the half cock notch. I handled one of Chuck's guns, with a Queen Anne lock, at the trade faire a coupla years ago. That lock caught on the half cock notch, especially when the cock was let down gently. Otherwise, I don't know enough about them to comment.
God bless
